    • fontStyles

      static final float[] fontStyles
      Contains threshold value for the various Font styles. If a given style is in an interval, then it is mapped to the style at the top of that interval.
      See Also:

    • svgStyles

      static final String[] svgStyles
      SVG Styles corresponding to the fontStyles

    • fontWeights

      static final float[] fontWeights
      Contains threshold values for the various Font weights. If a given weight is in an interval, then it is mapped to the weight at the top of the interval.
      See Also:

    • svgWeights

      static final String[] svgWeights
      SVG Weights corresponding to the fontWeights

    • logicalFontMap

      static Map logicalFontMap
      Logical fonts mapping

    • COMMON_FONT_SIZE

      static final int COMMON_FONT_SIZE
      The common font size to use when generating all SVG fonts.
      See Also:

    • fontStringMap

      final Map fontStringMap
      Used to keep track of which characters have been rendered by each font used. MapKey is the fontKey, mapValue is a sorted array of used characters.

  • Constructor Details

    • SVGFont

      public SVGFont(SVGGeneratorContext generatorContext)
      Parameters:
      generatorContext - used to build Elements

  • Method Details

    • recordFontUsage

      public void recordFontUsage(String string, Font font)
      Records that the specified font has been used to draw the text string. This is so we can keep track of which glyphs are required for each SVG font that is generated.

    • createCommonSizeFont

      private static Font createCommonSizeFont(Font font)
      Creates a new Font that is of the common font size used for generating SVG fonts. The new Font will be the same as the specified font, with only its size attribute modified.

    • toSVG

      public SVGDescriptor toSVG(GraphicContext gc)
      Converts part or all of the input GraphicContext into a set of attribute/value pairs and related definitions
      Parameters:
      gc - GraphicContext to be converted
      Returns:
      descriptor of the attributes required to represent some or all of the GraphicContext state, along with the related definitions
      See Also:

    • toSVG

      public SVGFontDescriptor toSVG(Font font, FontRenderContext frc)
      Parameters:
      font - Font object which should be converted to a set of SVG attributes
      frc - The FontRenderContext which will be used to generate glyph elements for the SVGFont definition element
      Returns:
      description of attribute values that describe the font

    • familyToSVG

      public static String familyToSVG(Font font)
      Parameters:
      font - whose family should be converted to an SVG string value.

    • styleToSVG

      Parameters:
      font - whose style should be converted to an SVG string value.

    • weightToSVG

      public static String weightToSVG(Font font)
      Parameters:
      font - whose weight should be converted to an SVG string value. Note that there is loss of precision for semibold and extrabold.
